AI coding tools are incredibly useful. They can read your codebase, understand context across dozens of files, and make changes in seconds. They can also read your .env file. Your secrets/ directory. Your SSH keys. Your AWS credentials. Not because they're malicious — but because nothing stops them by default. I built uignore to fix this. What is uignore? uignore gives you a single .uignore file — same syntax as .gitignore — that blocks file access across all supported AI tools simultaneously. gitignore # .uignore secrets/ .env .env.* *.pem *.key Add a path once. Claude Code, Gemini CLI, Cursor, and Windsurf all respect it automatically. How it works Each AI tool has a native hook system: ┌─────────────┬────────────────┬─────────────────┐ │ Tool │ Hook │ Block mechanism │ ├─────────────┼────────────────┼─────────────────┤ │ Claude Code │ PreToolUse │ exit code 2 │ ├─────────────┼────────────────┼─────────────────┤ │ Gemini CLI │ BeforeTool │ exit code 2 │ ├─────────────┼───────────────
